' the following is a specification, reference being Vhad therein to the accompanying drawings, forming part of this specicatiomin which- Figure l is a view 1n side elevation of my Fig. 2 is a horizontal of Fig. 1. Fig. 3 is an end view. Fig. 4 is a cross-sectional view o n the line IV IV of Fig. 1. Fig. 5 'is a vertical cross-section on the line V V of Fig. 2. v

My inventionV relates'to the class of explosive-engines; and it is designed for the purpose of providing an engine-capable of im-V parting an Aimpulse to the mainshaft at each stroke front and back, whereby the poweris sively in each cylinder orits explosive-chamber, receiving an igniting-spark once during two revolutions at the proper moment.

The engine 1s deslgned to transmit power ygenerated in the explosion-chamber in a con-, 'stant succession of strokes lmparted to the v'crank-shaft, thereby Vobviating the' usual r delay incident to the functions; as carried 'out in fengin'es ofl single ordoublel cylinder construc- "tion, and, the transmission of the forces vis "maintained throughout lthe connected piston structure by means of anl intervening frame,

thus securing Iequal strain on the'working -parts lof the engineand'main shaft, while -full utilizing the generated power.' f The invention also refersv to the means 'whereby pairs ofthe cylinders are connected fso as 'to insure simultaneous explosions there- V4in and'assist in scavenging thelchambers.

' 'Referring' now to the drawings, 2 is the ymain frame' Vor base of the'engine, provided with journal-bearings?) at each side adapted `to support the Inain 'crank-shaft' 4. 'An-upper shell or frame 5 is secured upon the lower base 2, 'providing upper bearings for the shaft and likewise inclosing, with the base 2, the

entire crank-shaft chamber. AtA each end ofthe framework 2 and 5 on opposite sides of the shaft vare ianges 6, providing bases on common vertical planes, to which by flanges 7 the cylinders 8 are bolted. Thesev cylinders,- preferably four in number at'each end of the engine, are equally arranged, as shown in Fig. 3, and are each adapted to receive a l piston 9. There are'thus eight entire cylinders and a corresponding number of pistons, four on each side.` At their inner ends each of said .four pistons is secured t'o common platesl() l0, whereby the four pistons of each set are rigidly connected, and the .opposite sets'of pistons are connected by means of intervening longitudinalv bars or lframes 11 of any suitable construction, as clearlyshown in Fig. 2. By this arrangement two of the cylinders and their pistons on each side of the shaft are located in thesame horizontal plane, while the other pistons and cylinders are located equally above and below said plane, midway between them and in alinement vertically with the longitudinal center of the engine. rlwo of the horizontally-alining pistons on one side are provided with wrist-pins 12, to which are attached connecting-rods 13, connected at their other ends with the lcrank-pins of cranks 14 of the main shaft 4. By this construction it will be seen that if anl explosion occurs first in the chambers of one pair of horizontallydisposed cylinders, then at the next stroke in the chambers ofthe corresponding cylinders on the other side of the'shaft, then on the next stroke 'in the verticaily-arranged cylinders'onthe otherl side ofthe shaft, (between the first pairs of cylinders,) then onthenext or fourth stroke in the corresponding pair of verticallyv arranged vcylinders on the other side, in four'strokes or two complete revolu- IOO 'cyclewill occur inregular orderfa'ndthat thel wresulting ,power of theexplosionsiwill fbe'f'o'or- 'fric respondingly imparted to the main shaft in a regular equal manner.

Each cylinder is provided at its outer end with a valve-casing comprising a fuel-inlet at its inner end and actuated by a suitable cam 23. The cams 28 for each pair of valves are mounted, as'shown, on the outer opposite ends of independent cam-rods 24 24, located in suitable bearings 25 and operated through pairs of pinion-gears 26 26 and worm-gearing 2728 from thefmain shaft 4. Pinions 26l are mounted on shaft 24, carried in bearings 25', the shaft 24 being driven by its wormw7heel 28, actuated from main shaft 4 by gear 2 The explosion-chambers of the oppositelylocated pairs of cylinders are connected by means of communicating ports 29, (clearly shown in Figs. 2 and 5,) so that should the igniter in either chamber fail to operate combustion therein will be communicated by the explosion in the other chamber. By this means an explosion is always insured and the highest efficiency of the engine maintained. The communicating ports 29 also facilitate equalization of the pressure and volume of the explosive mixture and likewise assist in supporting either chamber from the other in case of any valve derangement at either side.

The construction and operation of the various subsidiary elements of the inventionto wit, the valve-actuating gearing, the inlet and exhaust valves, the igniter, the cooling elements, and governor-do not per se form essential portions of the present invention, and it will be understood that these may be adopted or utilized within the province of the designing engineer or builder.

If desired, a single pitman may be used, connected merely to the reciprocating pistonframe and with the crank, as will be readily understood. The cylinder and piston construction of one side only may also be used with good results, as will be understood, by merely eliminating the sets of cylinders and pistons of the other side.

The operation of the invention will be readily understood from the foregoing description and its advantagesl will be appreciated by all those familiar with this class of engines. It insures an impulse upon the cranks at each stroke and provides ample time for the performance of the various functions of each cycle. The engine is perfectly balanced. It is verycompact in construction, considering the available power, and is well adapted to installation with motor-vehicles. It is comparatively cheap, simple in construction, durable, and not liable to get out of order.

Changes and variations may be made in the design, proportions, or the various other details by the skilled mechanic, but all such are to be considered as within the scope of the following claims.
